REFRIGERATOR.

SPECIFICATION forming part of Letters Patent -No. 245,580, dated August 9, 1881.

Application filed May 3, 1881. tNo model.)

To all whom it may concern:

Be it known that I, GEORGE T. THAOKARA, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a vertical longitudinal sectional view of a refrigerator embodying my improvements, and Fig. 2 is a vertical transverse sectional view, of the same. Fig. 3 is a detail view.

The invention relates to refrigerators; and it consists in the improved features of construction and combination, hereinafter fully described, and particularly pointed out in the claims.

The object of the invention is to prevent dampness in the refrigerator by carrying Off' the heavier gases through adraft-pipe leading from the bottom to the top of the refrigerator, and at the same time condensing the lighter gases in a condenser or ice-chamber, dry air being supplied to the condenser or ice-chamber, as will be hereinafter fully set forth.

Referring by letters to the accompanying drawings, A designates the casing or body of the refrigerator, and B is a close-fittiu g cover for the same. Suitable doors are provided for the ice-chamber and for the receivin g-ch amber. The frames of these doors are provided with grooves a at the hinge side thereof, and the rear edges of the doors have beads 12, which enter said grooves when the doors are closed,

as shown in Fig. 3, for the purpose of preventing the doors from being removed, even when the hinges break or are taken off, and atthe same time make an air-tight joint.

The ice-chamber C is lined with zinc, and has an air-space, a, surrounding it. The bottom of the ice-cham her is provided with drip-bars, and beneath are drip-boards D in near V-shapc form. An air-space, c, is formed between the zinc and the drip-boards D.

Beneath the drip-boards D is an inclined trough, E, connecting with a drip-pipe, F, preferably located atone side of the refrigerator, and having at its bottom an air-cup, G, to pre vent the ascent of air.

The inner wall of the ice-chamber has an opening, e, between it and the removable top, to permit the lighter gases to be forced over this wall into the condenser or ice-chamber, to be there condensed and carried off with the drip.

H designates the air reservoir or chamber, having small inlet f and larger outlet 9, communicating with the ice-chamber at the top thereof.

I designates the draft pipe or stack, extending from the bottom of the receiving-chamber and opening at the top thereof. This pipe is preferably located in one corner of the receiving-chamber. Theheavier gases escape through thisdraft-pipe,while thelightergasesaretbrced over the inner wall of theice-chamber,and, being condensed in the ice-chamber, pass off with the drip, thus effectually preventing dampness in the refrigerator. I

By this construction a gentle indirect current is created throughout the refrigerator, and this cnrrentprevents the moisture or dampness attending refrigerators of ordinary construction.

The device is cheap and simple and effectually prevents dampness or moisture.

Having thus fully described my invention, what I claim is 85 1. In a refrigerator, the combination of the l air-reservoir, the ice-chamber surrounded by the air-spaces, the draft-pipe, and the drippipe having the air-cup at its bottom, substantially as and for the purposes set forth. o

In a refrigerator, the air-passage H, having its inlet f smaller than its outlet g, substantially as and for the purpose set forth.
